Henry’s Law Constant Calculator
Divide the concentration of the gas in the liquid by its partial pressure to find the Henry’s law constant.
The Henry’s Law Constant Calculator determines the solubility of a gas in a liquid relative to its partial pressure above the liquid. This principle is widely used in fields such as chemistry, environmental science, and engineering to predict gas behavior in solutions.
Formula:
k = C / P
| Variable | Definition | Units |
|---|---|---|
| k | Henry’s law constant | mol/(L·atm) |
| C | Concentration of gas in the liquid phase | mol/L |
| P | Partial pressure of the gas | atm |
Solved Calculations:
Example 1: Calculating for oxygen dissolved in water at a concentration of 0.0013 mol/L and a partial pressure of 0.21 atm.
| Step | Value | Explanation |
|---|---|---|
| Concentration (C) | 0.0013 mol/L | Given concentration of oxygen in water |
| Partial Pressure (P) | 0.21 atm | Atmospheric pressure of oxygen |
| Henry’s Constant (k) | 0.00619 mol/(L·atm) |
Example 2: Finding for carbon dioxide at a concentration of 0.034 mol/L and a partial pressure of 1 atm.
| Step | Value | Explanation |
|---|---|---|
| Concentration (C) | 0.034 mol/L | CO dissolved in water |
| Partial Pressure (P) | 1 atm | CO gas partial pressure |
| Henry’s Constant (k) | 0.034 mol/(L·atm) |
